Each piston crown is carefully inspected, measured, and tested to identify wear, deformation, or cracking. A detailed inspection report is prepared to define the repair scope.
Critical areas such as ring grooves, outer and inner diameters, and combustion surfaces are pre-machined to ensure proper alignment and preparation for further restoration.
Approved welding procedures, including submerged arc and MIG/TIG welding, restore worn or damaged areas. Controlled heat treatment relieves internal stress and ensures structural stability.
CNC machining restores the parabolic crown profile and all critical dimensions to required tolerances, ensuring correct fit and performance.
Existing chromium layers in ring grooves are removed and replaced with a new double chromium layer to improve wear resistance and extend service life.
Final dimensional checks, visual inspection, and quality control are completed. All results are documented in a clear final report.
